[linux-lvm] Problem copying device files to an LVM volume

[Don Williams]

Hello all,

 When I copy device driver files files via NFS to a LVM volume they are "interpreted" instead of copied.  The
result is that when the copy hits the sda driver it starts copying the entire contents of /dev/sda drive!  Instead
fo the /dev/sda file itself.  

 The file that it's trying to copy is from Tom's Rescue CD kit.   The dev files are sources files for creating a
bootable rescue CD.  

 My configuration is: 

 debian linux 3.0,  Kernel v2.4.17    Using ReiserFS 3.6.x  (I also tried using the EXT2 fs with identical results)


The SOURCE dir is about 5GB in size.  I'm trying to copy that to a 50GB LVM volume via the network
(NFS) .  However it consumes the whole 50GB.   If I remove the offending directories it returns to the proper size.
  Suggestions?

  Regards,
